Re: What Are Lubricants Used For
I would like to tell you about that, What Are Lubricants Used for machines, as you want. Here I am giving you information about it, as you want. Lubricant; A lubricant is a substance introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property of reducing friction is known as lubricity. In addition to industrial applications, lubricants are used for many other purposes. Other uses include cooking (oils and fats in use in frying pans, in baking to prevent food sticking), Bio-medical applications on humans (e.g. Lubricants for artificial joints), Ultrasound examination, Medical examinations, and the use of personal lubricant for sexual purposes. Properties A good lubricant generally possesses the following characteristics: High boiling point and low freezing point (in order to stay liquid within a wide range of temperature) High viscosity index Thermal stability Hydraulic stability Demulsibility Corrosion prevention High resistance to oxidation Additives Main article: Oil additive Antioxidants Detergents Anti-wear Metal deactivators Corrosion inhibitors, Rust inhibitors Friction modifiers Extreme Pressure Anti-foaming agents Viscosity index improvers Demulsifying/Emulsifying Stickiness improver, provide adhesive property towards tool surface (in metalworking) Complexing agent (in case of greases) Types of lubricants Base oil groups Biolubricants made from vegetable oils and other renewable sources Synthetic oils Polyalpha-olefin (PAO) Synthetic esters Polyalkylene glycols (PAG) Phosphate esters Alkylated naphthalenes (AN) Silicate esters Ionic fluids Multiply alkylated cyclopentanes (MAC) Applications Lubricants perform the following key functions: Keep moving parts apart Reduce friction Transfer heat Carry away contaminants & debris Transmit power Protect against wear Prevent corrosion Seal for gases Stop the risk of smoke and fire of objects Prevent rust.
